Chlorides call compounds of metals with chlorine. Chlorides are salts. Chlorine atoms as a part of chlorides can be interpreted as acid residues of hydrochloric acid. Thus, chlorides can be considered as salt of metals and hydrochloric acid. To receive chloride in house conditions does not make particular problems. The simplest in receiving is sodium chloride.
It is required to you
- Hydrochloric acid (is on sale in pharmacies). A sodium hydrocarbonate (baking soda, is on sale in shops). Glass retort. Glass or steel shovel or spoon.
Instruction
1. Prepare solution of hydrochloric acid. If the acid concentrated it needs to be diluted. Pour water in a retort. Add acid a thin stream, constantly stirring slowly with solution. If saltacidsthe solution which is not concentrated just pour it in a retort. The number of solution of hydrochloric acid in a retort has to be not large to exclude its slopping outside when passing reaction.
2. Prepare a sodium hydrocarbonate. Usually it is powder, but it has property to slezhivatsya at hit of moisture with formation of lumps. If powder of a hydrocarbonate of sodium contains lumps, remove them or break into small parts.
3. Carry out reaction of neutralization of solution of hydrochloric acid by a crystal hydrocarbonate of sodium. Pour in the small portions a sodium hydrocarbonate into a retort. There will be rather impassioned reaction to allocation of a large amount of carbon dioxide. After addition every portion of a sodium hydrocarbonate, wait for full passing of reaction and slightly shake up solution. When reaction ceases to go, stop sodium hydrocarbonate powder addition. In a retort sodium chloride solution, that is, usual table salt was formed.
